Collective behaviour of phoretically active colloids

Abstract

Interfacial phoretic transport mechanisms can be used to design self-propelled active colloids, due to their force-free nature. In my talk, I will discuss the generic properties of such self-propelled colloids, and examine their collective behaviour when they interact via the gradient of the fields that they also use for self-propulsion. I will present some results on interesting collective effects such as instabilities and emergent dynamical behaviours.
